Append filenames with folder name [dont understand] - applescript

Question

Im struggling to understand how to rename(append) filenames inside a folder with the folders name.
Eg, about.txt, picture.jpg, etc to become folderName-about.txt, folderName-picture, etc.
Im a complete noob at applescript, this is my first script ever!
on run {input, parameters}
tell application "Finder"
set theFolder to folder "OS X:Users:David:Desktop:SCRIPT:script-copy"
set targetFolder to folder "OS X:Users:David:Desktop:SCRIPT:script-copy-finished"
display dialog "Which structure do you wish to duplicate?" buttons {"Structure-MAIN", "Structure-OTHER"}
set chosenStructure to button returned of result
if contents of chosenStructure is equal to "Structure-MAIN" then
set chosenStructure to "OS X:Users:David:Desktop:SCRIPT:script-copy:-MAIN"
else
set chosenStructure to "OS X:Users:David:Desktop:SCRIPT:script-copy:-OTHER"
end if
display dialog "Specify a new folder name:" default answer "John The Dog"
set newName to (text returned of result)
set createNewStructure to make new folder at targetFolder with properties {name:newName}
duplicate every file of entire contents of folder chosenStructure to createNewStructure
set the_folder to name of folder chosenStructure
repeat with this_file in (get files of entire contents of folder chosenStructure)
set the_start to offset of "_" in ((name of this_file) as string)
set the_stop to count (name of this_file as string)
set name of this_file to (the_folder & (items the_start thru the_stop of (name of this_file as string)))
end repeat
end tell
return input
end run
Thanks for your help!

Answer 1

I want all filenames inside the folder to have the folders name
prepended at the beginning of the filename. Eg, about.txt to become
folderName-about.txt, etc.
Try this:
tell application "Finder"
...
set the_folder to name of createNewStructure
repeat with this_file in (get files of entire contents of createNewStructure)
set name of this_file to the_folder & "-" & (name of this_file)
end repeat
end tell
The whole Script:
set theFolder to ((path to desktop) as text) & "SCRIPT:script-copy"
set targetFolder to ((path to desktop) as text) & "SCRIPT:script-copy-finished"
display dialog "Which structure do you wish to duplicate?" buttons {"-MAIN", "-OTHER"}
set chosenStructure to ((path to desktop) as text) & "SCRIPT:script-copy:" & button returned of result
display dialog "Specify a new folder name:" default answer "John The Dog"
set newName to (text returned of result)
tell application "Finder"
set createNewStructure to make new folder at targetFolder with properties {name:newName}
duplicate every file of entire contents of folder chosenStructure to createNewStructure
set the_folder to name of createNewStructure
repeat with this_file in (get files of entire contents of createNewStructure)
set name of this_file to the_folder & "-" & (name of this_file)
end repeat
end tell
